The bipolar output enables the LT8714 to source or sink current, regardless of the output voltage polarity. Applications include bidirectional current sources, test systems, high power low frequency signal amplification, back body biasing, thermoelectric coolers and electronic window tinting.
The LT8714 is available in a 20-lead TSSOP package, operates over a 4.5 to 80V input voltage range and produces an output voltage that is dependent on the choice of external components. This device can operate as a power source and as a load irrespective of the voltage polarity. Its rail-to-rail output current monitor and control enables the device to be configured as a current source.
The fixed operating frequency, selectable from 100 to 750kHz, can be synchronised to an external clock. The LT8714 incorporates a power good output signal to indicate if the output voltage is above or below its target regulation voltage. Additional features include overcurrent protection, undervoltage lockout and soft-start.
